6 Things to Know About Saltwater Pool Salt Levels

3000–4000 ppm is the sweet spot Around 3200 ppm is ideal for most systems, but anything in that range works.

Saltwater pools are not like the ocean Ocean water is about 35,000 ppm. You are just using salt to generate chlorine via the cell.

Too low burns out the cell If salt drops below 2500 ppm, the cell works too hard and fails sooner.

Too high causes corrosion or salty taste High salt levels can corrode fixtures and make the water taste salty.

Test monthly with strips or a digital meter Add pool salt only when needed. Never use table salt, which has anti-caking agents.

Clean the salt cell every few months If your water is hard, clean the cell regularly to keep it working efficiently.
